Cleaning, with sand?

[kayleenxx]

So I have a three year old rescue that has lived in sand her whole life, has been doing fine, and for the time being, i'm going to keep it that way, perhaps i'll change it one day but not anytime soon. My curiosity has led me to the question: When cleaning the tank, what do I do with the sand? :?:

Replace it all, this is the only way to be sure that bacteria isn't festering in your dragons home. You can take everything out and shop-vac out the sand.
